My work concerns forms of psychic unity and disunity. I am presently working on several projects on dissociative identity disorder, on pretense and imagination, and on the role of higher-order beliefs in self-deception on so-called "avowal accounts" of the phenomenon. 

I have just completed work on a monograph on split-brain phenomenon, Self-consciousness and “Split” Brains: The Minds’ Ipublished summer 2018 by Oxford University Press.

The split-brain phenomenon has tantalized philosophers because, on the one hand, split-brain subjects behave under experimental conditions as if they had two conscious minds apiece, and, on the other hand, a split-brain subject nonetheless seems more or less like a single one of us at the end of the day. Philosophers have overwhelmingly assumed that one of these impressions must be mistaken—that where there is one person, in other words, there can be no more than one mind or thinker. Although this is surely right as a general rule, the book argues that split-brain subjects constitute principled exceptions to it: a split-brain subject is (composed of) two thinkers is one person, because these two thinkers do not recognize each other’s existence. (Research on the book has been supported in part by the Quinn Fellowship at the National Humanities Center during the academic year, 2014-2015.)

Several of my works also concern conscious unity, the relationship between the unity of consciousness and the identity of subjects of experiences, and the possibility of conscious disunity.
